<span class="Comment">MODULE: GF2XVec</span>

<span class="Comment">SUMMARY:</span>

<span class="Comment">The class GF2XVec implements vectors of fixed-length GF2X's.  You can</span>
<span class="Comment">allocate a vector of GF2X's of a specified length, where the maximum</span>
<span class="Comment">size of each GF2X is also specified.  These parameters can be specified</span>
<span class="Comment">either with a constructor, or with SetSize.  It is an error to</span>
<span class="Comment">try to re-size a vector of non-xero , or store a GF2X that doesn't fit.  </span>
<span class="Comment">The space can be released with &quot;kill&quot;, and then you are free to call SetSize</span>
<span class="Comment">again.  If you want more flexible---but less efficient---vectors, use</span>
<span class="Comment">vec_GF2X.</span>
